Modelling of the Hypothalamic-Pituitary-Adrenal Axis Perturbations by Externally Induced Cholesterol Pulses of Finite Duration and with Asymmetrically Distributed Concentration Profile
(Maik Nauka/Interperiodica/Springer, New York, 2017)
A model was developed that can be used to study the effect of gradual cholesterol intake by food on the HPA axis dynamics. Namely, well defined oscillatory dynamics of vital neuroendocrine hypothalamic-pituitary-adrenal ...
Mixed-mode oscillations and chaos in return maps of an oscillatory chemical reaction
(Maik Nauka/Interperiodica/Springer, New York, 2015)
The return maps, as an element of mathematical phenomenology appropriate for general examinations of complex dynamic states of the oscillatory systems were used to detect and explain the evolution of mixed-mode oscillations ...
Intermittent Chaos in the Bray-Liebhafsky Oscillator. Dependence of Dynamic States on the Iodate Concentration
(Maik Nauka/Interperiodica/Springer, New York, 2017)
Chaotic dynamic states with intermittent oscillations were generated in a Bray-Liebhafsky (BL) oscillatory reaction in an isothermal open reactor i.e., in the continuously-fed well-stirred tank reactor (CSTR) when the ...
Dynamic behavior of the bray-liebhafsky oscillatory reaction controlled by sulfuric acid and temperature
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The non-periodic, periodic and chaotic regimes in the Bray-Liebhafsky (BL) oscillatory reaction observed in a continuously fed well stirred tank reactor (CSTR) under isothermal conditions at various inflow concentrations ...
Activity of polymer supported cobalt catalyst in the Bray-Liebhafsky oscillator
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The infuence of poly-4-vinylpyridine-co-divinylbenzene-Co2+ catalyst on the Bray-Liebhafsky (BL) oscillator used as the matrix for establishing catalyst's activity was analyzed. The addition of the catalyst do not change ...
Effect of the support and the reduction temperature on the formation of metallic nickel phase in Ni/silica gel precursors of vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Ni/SiO(2) materials with identical composition (SiO(2)/Ni = 1.0) have been synthesized by precipitation of Ni(NO(3))(2) center dot 6H(2)O solution with Na(2)CO(3) solution on the silica gel, obtained at three different pH ...
Temperature dependence of catalytic cyclohexane partial oxidation in a polytetrafluoroethylene reactor
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Polymer-supported Co(II) catalyst was prepared and its activity and selectivity in the partial oxidation of cyclohexane was determined at several temperatures in a polytetrafluoroethylene reactor ( PTFE). The catalyst was ...
Methanol electrooxidation in alkaline solutions on platinum-based electrodes: Classical and dynamical approach
(Maik Nauka/Interperiodica/Springer, New York, 2013)
The electrochemical oxidation of methanol has been carefully studied due to its application in fuel cells. In this work electrooxidation of methanol was investigated on bare platinum electrode, the platinum electrode covered ...
Numerical evidence of complex nonlinear phenomena of the Belousov-Zhabotinsky oscillatory reaction under batch conditions
(Maik Nauka/Interperiodica/Springer, New York, 2013)
By numerical calculations based on our previously proposed model with Br2O intermediate species we were able to simulate complex evolution of the Belousov-Zhabotinsky (BZ) reaction under batch conditions. In the defined ...
The stability of the extended model of hypothalamic-pituitary-adrenal axis examined by stoichiometric network analysis
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Stoichiometric network analysis (SNA) represents a powerful mathematical tool for stability analysis of complex stoichiometric networks. Recently, the important improvement of the method has been made, according to which ...
